The set-up comes from the closed guard, controlling the kimono and clamping down your elbows on the thighs. Post up one leg off to an angle to the rear, controlling strongly with the same side hand — the trap. The other leg positions forward roughly 90° from the rear leg, driving forward while pushing the guard leg down — the jam. The jam knee pushes forward and rolls to the floor, pinning the leg. The arm on this side controls your opponents head while your other arm shields the trap leg. The trap leg either steps out inverting the hips briefly before reestablishing the side mount, or the trap leg can pin the leg already pinned the by the jam foot, completing the pass in a more subtle fashion.
If they attempt to open the guard preemptively and place the foot in the hip, reach your hand back and scoop the foot up setting it in the trap position. Use the other leg to set-up the jam. Using this idea we covered a drill for the trap and jam. Your partner attempts to set the foot in the hip and you pull the leg up and trap. Then switch sides allowing your partner to post in the opposite hip which you again trap and jam on this side.
Another variation came from the standing pass, with your feet on either side of their hips, pushing forward so that your opponent knees are pushed towards their face. Control their lapels and ride each time they try to bump you back, your legs flexing and bending in response to their attempts to push you backward. Then obtain cross collar grab and same side pant leg control. Drive their foot down and make them spin, drop your knee across their thigh, sliding through to pass.
Next Ultimate Fighter 12 alumnus Kyle Watson covered passing from the same side underhook half guard. Kyle first showed an escape from the mount. Setting up an L-frame with a hip bump while switching out to the hip on that side. Use your top foot to drag the leg into the half guard while pushing down your partner's leg placing them in half guard. The bottom player posts up on their elbow to create pressure to attack from the half guard. This space allows the top player to feed their arm through and grip the gi pulling them flat to the mat while shooting the free leg out to stabilize. Thus setting up the same side underhook.
From here walk the trapped leg foot to your opponents rear, use the hand on this side to free your knee by controlling their pants. They may block your knee, so rather than trying to fight through it, roll your knee laterally and perpendicularly to their pressure, placing the knee on the mat. Under hook their blocking arm and walk your fingers superiorly in an arc to obtain high under hook control. There are now three ways to pass:
- Free leg cross pass
- Posting on your forearms and head, pike up and drive the knee of your free leg through to the opposite side. Bring this foot through the hole between your trapped leg and your opponent's body. Drive this leg all the way through, placing you in a hurdler stretch and creating a great deal of pressure on their chest. This pressure should allow you to free your trapped foot.
- Trapped leg cross pass
- In this case you again post as before, pike up and drive the knee of your trapped leg though to the opposite side. Post your free leg out, creating tripod, use this foot to free your trapped foot.
- Straight to mount
- Create a base with your under hooks and head, slide forward placing your chest on your opponent's face, creating space between their legs and your bottom. Your free foot loops inside, posting on their hip pulling them flat and freeing the trapped leg as you transition into mount.
Finally Jack McVicker showed some gi deviltry once again:
- Rear ozeki
- With your opponent in four points position and you hip-to-hip, shoot your cross hand under their arm to the far side of their neck. Step up and use this hand to grab inside of the sleeve of the opposite arm, which drapes across the back of their neck. Fall to your side to finish the choke.
- Rear mount arm bar
- From the same position as above, obtain the cross collar control under their arm. Step your same side leg next to their shoulder and step around their body placing the shin of your opposite leg next to their head. Sit and pull them into arm bar, allowing your knee to sag out and then pop over their head.
- Rear inverted cross collar choke
- Your opponent starts in four points, start in north-south position obtaining cross collar neck and under arm control. Spin 90° away from the hand controlling the neck, then sit back putting your leg over their head and the opposite leg over the posterior to provide counter pressure.
- Arm defense counter offense
- You have obtained arm bar from mount but your opponent defends by arm triangleling the threatened arm and tucking your free hand behind the superior knee. Cross your ankles to obtain control, grab the wrist of the unthreatened arm and control sleeve with your free hand. Open your legs and pull to your hip, placing their unthreatened elbow over their sternum. Pull your attacking arm out and pin it to their chest. Switch to the S-mount attacking the opposite side. Wrap the top pinned arm and set-up the arm bar on the opposite side. Of course if they defend you can consider returning to the original side and reattacking the original arm.
